I, David Liu, the principal executive officer of LaserSight Incorporated certify
that:

1. I have reviewed this quarterly report on Form 10-QSB of LaserSight
Incorporated;

2. Based on my knowledge, this report does not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements made, in light of the circumstances under which such statements
were made, not misleading with respect to the period covered by this report;

3. Based on my knowledge, the financial statements, and other financial
information included in this report, fairly present in all material respects the
financial condition, results of operations and cash flows of the registrant as
of, and for, the periods presented in this report;

4. The registrant's other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial
reporting (as defined in Exchange Act Ruled 13a-15(f) and 15d-15(f)) for the
registrant and have:

            a) Designed such disclosure controls and procedures, or caused such
      disclosure controls and procedures to be designed under our supervision,
      to ensure that material information relating to the registrant, including
      its consolidated subsidiaries, is made known to us by others within those
      entities, particularly during the period in which this report is being
      prepared;

            b) Evaluated the effectiveness of the registrant's disclosure
      controls and procedures and presented in this report our conclusions about
      the effectiveness of the disclosure controls and procedures, as of the end
      of the period covered by this report based on such evaluation; and

            c) Disclosed in this report any change in the registrant's internal
      controls over financial reporting that occurred during the registrant's
      most recent fiscal quarter that has materially affected, or is reasonably
      likely to materially affect, the registrant's internal controls over
      financial reporting; and


5. The registrant's other certifying officer and I have disclosed, based on our
most recent evaluation of internal control over financial reporting, to the
registrant's auditors and the audit committee of the registrant's board of
directors (or persons performing the equivalent functions):

            a) All significant deficiencies and material weaknesses in the
      design or operation of internal controls over financial reporting which
      are reasonably likely to adversely affect the registrant's ability to
      record, process, summarize and report financial information; and

            b) Any fraud, whether or not material, that involves management or
      other employees who have a significant role in the registrant's internal
      controls over financial reporting.
